Ingredients You’ll Need
To make the most flavorful slow cooked steak fajitas, you’ll need a few simple ingredients that come together to create magic in your crockpot. These ingredients will ensure that your beef fajitas turn out juicy, tender, and packed with Tex-Mex goodness
- Flank Steak: You can substitute with skirt steak if preferred.
- Yellow Onion: White onions can be used as a substitute.
- Red Bell Pepper & Green Bell Pepper: Offers a sweet taste and tender texture. You can use any color bell pepper. For a spicier version, chop up a jalapeño and mix it in with the other peppers.
- Tomato Salsa: Marinating the beef in the salsa brings all the flavors together. Use your favorite kind for the best results.
- Beef Broth: Keeps the meat moist and adds richness to the sauce. Vegetable broth or chicken broth will also work.

Equipment
Notes
- Sear the meat: For added depth of flavor, sear the fajita meat in a hot skillet before placing it in the slow cooker. This step caramelizes the surface and locks in the juices.
- Make extra for leftovers: These fajitas taste great the next day. Make a larger batch and enjoy easy meals throughout the week.
- Add citrus: Squeeze some fresh lime juice over the fajitas just before serving. The acidity brightens up the flavors and adds a fresh note.

I recently made fajitas too… next time I try it in the crockpot. 🙂
Excellent Kate!
Great recipe! I love slowly cooked beef!
Absolutely perfect. And so easy. Our kind of weeknight meal, looks so good!
It’s nearly summer and I’m getting all sorts of wintery recipes from up north. Even in the summer, I use my slow cooker. I put it in the laundry room/store room and there’s no heat in the kitchen.
Now… I LOVE fajitas. Not a lot of Mexican or even Spanish food where we live in Australia so I’ve always made my own. What you’ve done here means I have more time to work and don’t have to stand over a hot stove. Cool!
Hi Maureen!!
I was in Melbourne about 10 years ago and I remember trying to find a taco place for hours… no luck! 😀
This is my kind of dinner! Fix it and forget it and then totally delicious!

This would be great for those Saturday afternoon get togethers when you don’t have any idea when anyone is arriving but you don’t want to be cooking when they get there. I’m going to try it with chicken or maybe a pork loin roast??
Oh I’m tight with my slow cooker. It was one of the first major kitchen appliances that I bought and I love it. It solves all problems. These fajitas look amazing!
I love fajitas and there’s nothing better than letting the crock pot do all the work! 😉
Nothing beats slowly simmered chicken or beef shredded and put into tortillas.
My slow cooker and I are BFFs too right now! Adding these fajitas to our menu! They look soooooo goooood!
